The Glenariff Iron Ore and Harbour Company began operating the railway line in 1873, it was the first and highest operational narrow gauge (3 feet) railway in Ireland. It was built to transport iron ore from several mines in the townland of Cloughcorr at the top of the glen down toCarrivemurphy Pier where it was loaded manually by chute onto schooners and exported to supply iron works in Scotland and England. The railway was cut down the south-eastern side of Glenariff and ran for a distance of approximately 4 miles (6.5km), crossing over the coast road by the White Arch, the piers of which you pass through when entering or leaving Waterfoot. The broken and storm battered remains of the old quay can still be seen on the shore.
